were seen upon the loaves still continuing their work; at the same time 

 were found in Conway numerous beetles, which proved to be a species of 

 Haltica, eatins: the leaves on the same alders. Tlie larvae which had 

 rava"-ed these shrubs were doubtless those of the Haltica before named. 

 These larvaa, when fully grown, were about half an inch long, nearly cylin- 

 drical, livid brown above, paler beneath, with six true legs and an anal 

 prolog. The body tapered somewhat at each extremity. Segments twelve. 

 Fourth and following, each with a transverse, oval, ventral, rough space, 

 forming a series of fiilse abdominal prologs. Each segment with a double 

 dorsal row of acuminated tubercles, or small points, bearing \ery short hairs, 

 and a single ventral series on each of the ventral plates. Head, tubercles 

 and true legs black. Lives exposed on leaves of the alder, the substance of 

 which it devours, leaving only the net-work of veins untouched. Conway, 

 August 4th, 1854. 



Selandria vitis Harr, 



July 29th, 1827. Found the full grown larvaj on the leaves of the grape 

 vine, gregarious, living on the under side of the leaves, and devouring, all 

 parts of them, beginning at the edge. Color of larvaj pale yellow, darker 

 or greenish on the back; first three segments, antepenultimate and i^cnulti- 

 mate deeper yellow; head and tail above black; legs greenish; segments, 

 twelve intermediate, each with two transverse rows of about six black spots 

 tipped with a short, thick, blunt bristle, excejit the first segment next the 

 head, which has only one row, the other row being incomplete, or wanting 

 the two superior spines. Last segment, or tail, with two spines or blunt bris- 

 tles. Prologs fourteen, and a bifid anal one; true logs six, in all twouty-two. 



July 3, 1831. Saw the gregarious larva? feeding bL'uc;itli the leaves of 

 the grape vine, five or six in a cluster. They eat the vine leaf, nervures 

 and tendrils, from the edge down to the peduncle. At the same time dis- 

 covered what I supposed to be the jjorfect insects on the leaves. Propedes 

 sixteen, true feet six, in all twenty-two feet. Length half an inch; above 

 pale bluish green, except the thoracic segments and jwstorior half of the an- 

 tepenultimate with the anterior half of the penultimate leg-bearing segments, 

 which arc pale yellow ; body beneath pale yellow or greenish. Head black ; 

 two rows of spiniferous tubercles (six in each transverse row) across each 

 segment; the tubercles black and produced into an acute, short, black spine. 

 Tip of last segment above anal prologs black. Larva and imago, July 20, 

 1827, July 24 — Aug. 4, 1832. S five twentieths of an inch. ? three tenths. 



Selandria rosoe Harr. 



May 21tli, Ibund Hies on rose bush. June 22d, found slugs on the same ; 

 probably hatched two or three days. July 8th, larvae disappeared. July
